To all whom 'it may concern:

Be it known that I, JACOB A. F ULfroN, a citizen of the United States, and a resident of Astoria, in the county of Clatsop and State of Gregon, have invented a certain new and useful Surgical Implement, of which the following is a full, clear, and exact description.

Among the principal objects of the present invention are: to provide an instrument for local application of heat for thethera-- peutic treatment of disease: to provide an appliance for controlling the applied'heat, and for regulating the same: and to provide internally applied is accurately disclosed.

One embodiment of the present invention is disclosed in the construction illust-rated in the accompanying drawings, forming a partof this spe'ciiication, in which- Figure l is a diagrammatic View of an instrument constructed and arranged in con'- formity with the present invention; Fig. 2 is a perspective view of a casing for the heating coils, adapted for internal insertion; Fig. 3 is a side view, partly in sectiomof a `with the casing illustrated in Fig. 2'; Fig. 4 is an 'enlarged 'cross sectionfef the casing illustrated in Fig. 2, havinglpositioned thereon the applicator illustrated in Fig. 3; and Fig. 5 is a cross sect-ion in 'diagram of a heating pad for external application.

In many cases, it is desired to locally treat by heat applications, internal surfaces of the human body. Heretofore anobjection has arisen in that the applications have' been attended by the riskl of over-heating and thereby inflicting injury to the very delicate membrane usually'covering the surface ot the parts thus treated. .This objection is obviated in the present invention, which employs a thermometer,- 6, of suitable construction, the bulb whereof is incased within a box l7. The boX 7 is provided with two terminal binding posts 8, 9. These terminal binding posts form the terminals box 7. The resistance coil 10 is placed in circuit with'the resistance coil 11,.Which is mounted lengthwise of the tube 12, substantially as illustrated in Fig. 1 of the drawglshe coil 1l is provided with terminal binding posts 13 and 14, the former of which is connected by means of the Wire 15` with the binding post 9, of the coil 10. The binding post 14- is connected to the binding post 1G by means of the wire 17. The binding post 16 and the binding post 18 i'orm the terminals .of the operating circuit of the rheostat 19. The rheostat 19 is placed in circuit with the lamp 20, by means of the wires 21, 21, which are connected to a suitable connection plug of the street, or other electric service.

The laminations of coils of wirewhich constitute the heating element within the tube` 1.1, are electrically separated by any known and su'liicient means. The wire cmployedl maybe of any approved make, that preferred by me being a good quality of German'si'lver. i

v In Fig. 2 of the drawings. I have show-n the casing l1 as havinga groove 22, formed inthe external side thereof. This groove is intended to receive and hold the applicater 23. It is also intended to receive and hold a small thermometer, when desired. The applicator 23 is a small tube, through the central opening in which may be forced medicine when desired. When heat applications alone are being made, the applicator 23 is not employed. When medicating accompanies the heat treatment, the applicator is laid within the groove 22 prior to the saine being inserted.

The pad illustrated in FigQ has the arlrheostat 19 and the thermometer 6.

'The instruments to .which heaters constructed in accordance with this invention maybe applied, are generally those which are designed for insertion in the orifices of the human body.

With an instrument thus constructed and placed in operative position, the acting physician or patient having previously ascertained the relative heating capacity of the two coils 10 and 11, adjusts the rheostat 19 to permit more or less current to pass through the said coils to raise or lower the temperature as desired. In this operation the thermometer 6 registers the quantity of heat due tothe heating of the coil 10, and

thereby apprises the operator of the degree of heat produced in the coil l-l, the ratio between the heating capacities of the-two coils being known, as stated.

The introduction of the lamp 20 in the receiving circuit of the rheostat 19 is an old and well-known expedient.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

l. Asurgical implement comprising a hollow instrument for internal insertion, hav ing an external groove adapted to hold a medicinal applicator; an applicator adapted to rest within said groove and to have transmitted through the same a suitable medieine; an electrical heating coil Within said hollow instrument; an electric circuit connected with the terminals of said coil and with an electric source;an interposed heating medium, disposed in said circuit; and an exposed thermal register mounted in juxtaposition with said heating medium to indicate the heat radiated from said coil in said hollow instrument.

2. Asurgical implement comprising a hollow tube shaped for insertion in the cavities of the human body; 'an electric heating coil disposed in said tube; a second electric heating coil having a thermal-activity of known relation to thatV of the first mentioned coil; an exposed register .to indicate the heat radiation of said first mentioned coil; and an electric circuit embodying a.' controlling device and both of the said heating coils in series. A

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
